What treatment is best for nasolabial folds?

Lately, my nasolabial folds have been getting deeper, making me look tired and older than my actual age, so I am very worried.

It is especially bad when I smile, but the wrinkles look prominent even when I have a neutral expression. I also feel like my skin elasticity has decreased compared to before, and the hollowing out of my nasolabial folds is severe, so I am wondering what treatment I should get.

Which procedure would be best suited for my condition among fillers, lifting, and skin boosters? I feel like I really need to get fillers.

I previously got nasolabial fold fillers, but my face looked a bit unnatural, so I prioritize a natural improvement above all else. I do not want excessive volume or a drastic change in my facial impression.

I am curious about effective procedures or fillers for nasolabial folds, whether a single session is sufficient, what types are used, the cost, and reviews from those who have tried them.
